IMPROVEMENT IN APPARATUS FOR LEVELING MILLSTONES.

Specification forming part of Letters Patent No. 125,472, dated April 9, 1872.

Specification describing a new and useful Improvement in Apparatus for Leveling Millstones. invented by BENJAMIN H. MEITZLER and PHILIP L. Hoos, of Fort Seneca, in the count of Seneca and State of Ohio.

The object of this invention is to provide efficient and convenient means for leveling the grinding surfaces or faces of burr-millstones; and it consists in the mode of supporting, adjusting, and leveling the statt upon the stone, hereinafter more fully described.

111 the accompanying drawing, Figure 1 rep- .resents a. verticalsection of the device taken on the line :10 x of Fig. 2. Fig. 2 is a section on the line y y.

Similar letters of reference indicate corresponding parts.

A is the burr-stone. Bis the spindle, to the neck O of which the bed-plate of my apparatus is fitted. I) is the bed-plate, which is a round disk provided with set-screws e for adjusting the staff on the face of the stone. F represents curved stanchions, (four, more or less, in number,) the upper ends of which are attached to and support the vertical cylindrical block G. H is an inverted cup, which is fitted on the-block G, as seen in Fig. 1, provided with an adjusting thumb-screw, I, by which the cup is raised or lowered on the block. J is the staff, which is connected with the cup H by the curved bar K. This bar extends out horizontally on top of the stafl', and is fastened thereto by the thumb-screws L L. In the center of the staff, and "isible through a' suitable aperture in the bar, is a spirit-level, N, by which the face of the stafi' is leveled. The staff, being connected with the inverted cup H, (which cup is allowed to turn or revolve on the top of the block G,) maybe moved around the bed D over the grinding-face of the stone. The face of the st ait is covered with red or other coloring matter, so that wherever it touches it leaves a mark or colors the stone. The highest places or points on the face of the stone are thus ascertained, and theplaces are indicated where the stone should be picked down to make its surface even and of uniform height.

Having thus described our invention, We claim as new and desire to secure by Letters.
